How to Know That Your Wiring System Is Old

Homes that were built between 20-30 years ago probably need rewiring in their electrical home system. But, always have a professional electrician inspect your wiring system at least once in ten years to guarantee electrical safety. That said, here are some signs that your wiring needs replacement.

The ground fault circuit interrupter outlets are absent in bathrooms, kitchen, and other areas in your house that frequently get exposed to damp or wet conditions.


  • A burning smell from an electronic device.
  • Circuit breakers that trip or fuses that blow more frequently.
  • Dimming or flickering lights.
  • Houses that were built over forty years ago.
  • Switch plates that have discolored and warm-to-touch outlets.
  • Wiring that’s surrounded by building insulation.
  • Cracked, damaged, or missing wire insulation that exposes the metal part of the wire.

Dangers of Old Electrical Wiring


Easily Overloaded-most old homes have few electrical outlets since individuals did not use many electrical appliances back in the day. But nowadays, thanks to technology, homes are filled with many electrical devices that use significant amounts of power. Circuits in homes that have few electrical outlets are mostly overloaded. Note that while many homeowners use extension cords as circuits, overloaded circuits are extremely dangerous as they could cause fire hazards.


Reduced Protection-for many years, electrical wires were coated with a rubber protective. But with time, this coating starts deteriorating and crumbling leaving wires expose and increasing the chances of a fire starting. Thankfully, electrical wires nowadays are coated with PVC which doesn’t deteriorate fast hence exposing wires. But if your home was built more than 20 years ago, you should consider getting it rewired.


No Electrical Receptacle Grounding-when grounding is absent, electrical appliances risk damage should electrical surges occur. Grounding helps prevent electrical shocks when power is flowing through an improper path.


What Can Be Done?

If your house has old wiring, you need to call a professional electrician for an inspection. Homeowners should also replace extension cords where they’re permanently used. Additionally, all damaged switches as well as receptacles should be replaced. Also, you should change loose outlets that occur mostly in areas where cords are often plugged in and out. Again, individuals should invest in a new 200-amp electrical panel. But, those who can’t afford the budget of replacing their electrical panel can replace circuit breakers with arc-fault circuit interrupters.
